I. BACKGROUND
---------------------

Adobe Flash Player is a cross-platform browser-based application runtime
that delivers uncompromised viewing of expressive applications, content,
and videos across screens and browsers. It is installed on 98% of computers.


II. DESCRIPTION

VUPEN Vulnerability Research Team discovered a critical vulnerability
in Adobe Flash Player.

The vulnerability is caused by an integer overflow error in the
"copyRawDataTo()" method within the "Matrix3D" class when processing
malformed arguments, which could allow remote attackers execute arbitrary
code via a specially crafted web page.

CVSS Score: 10 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
